Shell-Waste Construction Tiles

Upcycling aquaculture shell waste into low-carbon construction tiles.

About this project

A promising circular-economy project that converts aquaculture shell waste into low-carbon construction tiles. Strengths include clear climate-relevant substitution potential and local value creation; gaps are limited methodological detail, unclear data-sharing and governance, and incomplete dMRV design — leading to a balanced integrity score of 70/100.

Score Reasoning — Dimensions

The headline score is a weighted sum of six integrity dimensions assessed by the Ozeaon Climate Intelligence System.

Scientific Rigor20% weight
75
Concept aligns with established waste valorization and cement-substitution literature, but lacks cited lab tests, durability assessments, or peer-reviewed validation specific to the proposed tile formulation.
Open Science15% weight
60
Project idea is simple, but the proposal gives no commitments to publish methods, datasets, or LCA models openly, limiting reproducibility.
Measurability (dMRV)20% weight
70
Impact is measurable in principle (mass of shells diverted, embodied carbon of tiles, avoided clinker), but no dMRV plan, baseline, or indicators are provided.
Additionality & Impact15% weight
65
Potential for real emissions reductions through substitution of higher-carbon materials and landfill avoidance, but additionality is unclear without information on current disposal pathways and market displacement dynamics.
Transparency & Governance15% weight
70
Business model implies traceable material flows, but the proposal omits ownership, funding, revenue-sharing, and verification mechanisms.
Community & Equity15% weight
75
Project inherently connects to aquaculture communities and can create local jobs and reduce pollution, but lacks explicit benefit-sharing, consent, or social safeguard plans.

Strengths

High circularity: turns an abundant waste stream into a value-added product, reducing landfill or disposal impacts.
Clear emissions-abatement pathway: substitution for clinker-based tiles or lowered embodied carbon is plausible and measurable.
Local economic opportunity: processing can create jobs and local enterprise for aquaculture communities.
Relatively low-technology barrier: tile manufacturing can be implemented at small-to-medium scale without exotic inputs.

Risks & Gaps

Insufficient methodological detail: no lab performance data (strength, freeze-thaw, water uptake) or lifespan estimates provided.
Data and verification gaps: no dMRV plan, baseline, or open-methods commitment — threatens credibility of claimed emissions benefits.

dMRV Recommendation

Tier

Tier 2 Operational

Cadence

Quarterly internal reporting (production, feedstock, energy use) with annual public LCA and verification; third-party verification annually or at major scale-up milestones.

Recommended

Yes

The project has measurable material and emissions flows but currently lacks a monitoring and verification plan. Tier 2 operational dMRV — combining batch-level digital tracking, process energy monitoring and a transparent product LCA with annual independent verification — fits this manufacturing/resource-substitution project: it is practical to implement, provides robust evidence for avoided emissions and product performance, and can scale with the operation.
